Features of XO25D050000GAHE11G


1. Standard 50 MHz High-Frequency Reference

50 MHz is one of the most widely used high-frequency clock references in communication systems (such as SDH/SONET standard clock), digital systems, and test & measurement equipment, with extremely broad compatibility.


2. Wide Supply Voltage Range (1.60~3.63 V)

Supports a wide input voltage from 1.6 V to 3.63 V, compatible with mainstream system supply voltages such as 1.8 V and 3.3 V, offering flexible application.


3. Low Power Consumption (Only 15 mA)

Maintains low power consumption even at 50 MHz high-frequency output, ideal for battery-powered and portable devices.


4. Wide Operating Temperature Range (-40~85℃)

Covers the full industrial temperature range, suitable for environments such as automotive electronics and industrial control.


5. Wide Storage Temperature Range (-55~125℃)

Broad storage conditions accommodate wider logistics and warehousing environments.


6. Low Annual Aging (±3 ppm/year)

Outstanding long-term frequency stability, reducing the need for periodic calibration and lowering system maintenance costs.


7. Fast Start-up Time (5 ms)

Reaches stable output within 5 ms after power-on, meeting fast system start-up requirements.


8. Industry Applications

With its 50 MHz standard high-frequency clock (SDH/SONET standard clock reference), wide supply voltage (1.6~3.63 V), low power consumption (15 mA), -40~85℃ wide operating temperature range, miniature 2520 package, Tri-State enable control, and 10 rigorous reliability tests, the XO25D050000GAHE11G is widely used in communication equipment (SDH/SONET networks), consumer electronics, automotive electronics, industrial control, IoT terminals, smart meters, and medical devices that require high-frequency stable clock references.
